To all when?, 'it may concern:

Be it known that I, l'lnNJAMiN l?. Minne, a citizen of the UnitedStates, residing at Sioux City, in the county of lVoodbury and ccitateet Iowa, have invented new and useitul mprovenients in @il Burners, otwhich the following is a specification.

This invention relates to liquid fuel burners, and has for its objectthe provision of a novel burner ior utilizing oil as a fuel, the burnerbeing adapted for use in connection with heating er cooking stoves,heating plants7 steam generators and the like, there being norestriction whatever as to the field of utility or the size whch maynaturally be varied to suit the requirements of the service desired.

An important object is the provision oi a burner which is provided withpriming means for .initially heating the Yfuel to ei!- iiectvaporization thereof so that it will be easily combustible7 means beingalso provided lor supplying the proper adminture of air to insurethorough combustion.

An additional object is the provision of a device ott this characterwhich will be sinrple and linexpensive to manufacture, easy to install,positive in action, etlicient and durable in service and a generalimprovement in the art.

llVith the above and other objects and advantages in view the inventionconsists in the details oi construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, inwhich:

Figure 1 is a side elevation ot the device showing it embedded within anash pit,

Figure 2 is a longitudinal section through the device alone in slightlyspaced relation thereto,

Figure 3 is a plan view of the burner with the top element thereofremoved.

teterring more particularly to the draw-n ings the numeral designates auel conducting pipe upon the upper end ot which is mounted my burnerstructure nwhich includes a disk 11 having a hub 12 surrounding acentral threaded bore 13 which is screwed ontothe pipe 10. This disk hasan upstanding peripheral ilange 14 so as to Told a small quantity of oiland to serve as a priming pan. Above the disk 11 is the burner properwhich comprises a disk 15 having a hub 1G formed with a threaded recess17 screwed onto the upper end of the pipe 10. At its center the disk isprovided with a small hole 18 which coinn'iuuicates with the recesstherein and which is for the outlet ot fuel. The top surface ot the disk15 is formed with a plurality or concentric grooves 19 so as to increasethe active surface to the inaximun'i. rthe burner further includes anupper disk 20 which nts upon thedisk 15 and which is held thereon by aplurality of lugs 21 formed upon the disk 20 and projecting over theedge ot the disk 15. This upper disk 2O is concaved on its underside soas to define a space 22 above the top surface ci the disk 15.

The device is intended to be mounted within the ash pit of a stove,furnace or the like or upon the grate but in any event l provide acylindrical sleeve 28 which is disposed about the pipe below the disk 11and which is embedded for the greater portion oit its height in a mass2li or ashes or the like so as to prevent air from entering at any placeother than through openings. at the upper edge or' the sleeve.

Assuming that the device has been 'constructed, assembled and installedas above indicated, it will be apparent that to eiiect starting, acertain amount of oil is poured into or allowed to flow onto the disk 11which constitutes the priming pan and this oil is ignited so that itwill burn and heat the entire device very thoroughly. l/Vhen the oil isthen turned on it will issue from the hole 18 and tlow onto the disk 15which has been heated` by the flame rising from the priming pan and thisheat will operate to vaporize the oil so that it will 'issue from theslight space between the disks 15 and 2O and burn to produce a sheetlike flame. The air entering through the openings 25 gives the properamount ot oxygen to insure proper combustion.

From' the 'foregoing description and a study oi' the drawings it will beapparent that I have thus provided a simple, inexpensive and easilyinstalled burner which will be highly eiiicient for the purposespecified and also for all kindred and analogous purposes and which onaccount of its simplicity and tewness oi' parts is not likely to get outet order.

While I have shown and described the preferred embodiment oi myinvention it is of course to be understood that 1' reserve the right tomake such changes in the form, construction and arrangement of lparts aswill `not depart from the spirit/,0f the inythe top surface of said diskbeing `formed l0 ventionprf'the scope of the subjOinedclaim. withconcentric lgrooves for increasing the Having thus described myinvention I aree and providing oil retaining means, :L
